An imaging device according to the present invention comprises a lens unit having a frame to which a lens is attached, an image sensor which ray of light that has passed the lens should enter, and a board member fixed to the frame of the lens unit, the board member being provided with an aperture for accommodating the image sensor, and the image sensor being adhered and fixed to the board member. Here, a protrusion which extends along an edge of the aperture is formed on a lens-side surface or a rear surface of the board member in at least a part of an area surrounding the aperture, and an adhesive is filled between the protrusion and the image sensor to fix the image sensor to the board member.

Imaging device

A printer apparatus includes: a platen roller around which paper sheets wind; a printing structure arranged for being drawn near to and away from the platen roller; a plurality of winding support members circumferentially disposed around the platen roller, for guiding a paper sheet to wrap around the roller; a sheet feed guide disposed in proximity to the printing structure and being pivotable substantially along the circumference of the roller; and a diverting mechanism for letting the sheet feed guide escape to a position such that it does not interfere with the printing structure in a print mode. The sheet feed guide is linked with a lever that pivots in a plane substantially perpendicular to the rotation axis of the platen roller, the lever having a fore-end protuberance.

Printer apparatus having platen roller with sheet feed guide

The invention provides a reel support drive mechanism which has a frictional power transmission mechanism,disposed in a power transmission path extending from a motor toward two reel supports,. The transmission mechanism,comprises a felt plate,interposed between a pulley,and PLAY and REV disks,which are rotatable relative to and coaxially with the pulley. The PLAY disk,is slidable in contact with an outer peripheral region of the felt plate,, and the REV disk,is slidable in contact with an inner peripheral region of the felt plate,. A one-way clutch spring,is provided between the PLAY disk,and the REV disk,. Power is output from the PLAY disk

Device for driving reel supports

A tension lever is pivoted to a chassis at one side of a reel support and has attached thereto in the vicinity of the pivoted portion opposite ends of a tension band reeved around the reel support. First and second two tension springs are provided between and fitted to a control lever and the tension lever each pivoted to the chassis and rotatable to different positions for different tape running modes. The second tension spring is fitted to the control lever with play in the direction of stretch of the spring. For reverse playback, the control lever rotates within the limits of play of the second spring to stretch the first spring only. The control lever stretches both the two springs for usual playback.

Tape tensioner for use in magnetic recording-playback device

A chassis is provided with a pair of leading guide blocks slidably fitted in respective guide slots for withdrawing a tape from a cassette, loading links for slidingly moving the respective guide blocks, and catchers arranged on the chassis at a loading completed position for the respective guide blocks to come into pressing contact with. Each of the loading links comprises a pivotal lever rotatably fitting around a pivot on the chassis and a link plate connected by a pivot pin to a free end of the pivotal lever and rotatably engaged at a forward end thereof with the guide block. The chassis is formed with apertures permitting insertion of the respective guide blocks therein, each covered with the catcher and each communicating with the guide slot. The aperture is positioned at a greater distance from the pivot than the forward end of the link plate when a center line L1 connecting the pivot and the pivot pin and a center line L2 connecting the pivot pin and the portion of connection between the guide block and the link plate extend toward the direction of loading in alignment with each other.

Loading mechanism of magnetic recording-reproduction apparatus and

A front mechanism mounted on a chassis loads a cassette in place by causing a first projection and a second projection on each of opposite side portions of a cassette carrying tray to slide along respective guide grooves formed in each of side plates. Power is transmitted from a drive cam gear provided on the rear side of the chassis to the tray via a drive mechanism, intermediate gear and rotary gear. For loading, the tray initially starts to move as inclined with the first projection and the second projection sliding along slanting grooves and is thereafter lowered by sliding movement of the projection along a vertical groove and sliding movement of the projection along a descent groove while being corrected from the inclined position to a horizontal position. Upon completion of cassette loading, the intermediate gear and the rotary gear constitute a Geneva stop, and the drive cam gear disengages from the drive mechanism. A support guide supporting the drive mechanism is provided by being formed by outsert molding inside the chassis and thereafter being rotated to project from a side portion of the chassis.

Cassette loading device for use in magnetic recording-reproduction

A chassis is slidably provided with a circular-arc control slide bulging toward a rotary cylinder and having projections spaced apart from each other. Reel supports and a reel drive mechanism are arranged on the curving-in side of the slide. Disposed on the path of movement of the slide is a drive cam gear formed with cam grooves each extending from an outer peripheral opening toward its center. The slide is formed thereon with a toothed projection which meshes with the cam gear during a period after one of the projections is fitted in the corresponding cam groove and until the other projection is fitted in the corresponding cam groove. The slide is further formed with a cam groove having engaged therein a soft brake lever for giving a light load to the reel support in REV mode, a brake lever for lightly braking a capstan motor in SLOW mode, a tension regulator lever for lightly braking the reel support in FF/REW mode, and a withdrawing lever for withdrawing a magnetic tape from a cassette for loading to operate these levers.

Magnetic recording-reproduction apparatus having a tape tension control

A magnetic recording/playback apparatus in which rotational torque from the drive shaft of a single motor is capable of being transmitted to a cassette loading mechanism and a tape loading mechanism includes a worm secured to the drive shaft and a worm wheel for being meshed freely with the worm, the worm wheel being provided with a toothless portion. The drive shaft is coupled to the cassette loading mechanism via the worm wheel. During operation of the tape loading mechanism by the drive shaft, the toothless portion of the worm wheel is brought into position opposite the worm wheel so that a driving force is no longer applied to the cassette loading mechanism. When a cassette is ejected, the toothless portion of the worm wheel is shifted after a tape loading operation, thereby reengaging the worm wheel and worm to actuate the cassette loading mechanism.
