A packing buffer member of the present invention is a packing buffer memberorthat is to be placed inside a packwith an object to be packedand includes first hollow convex partsand(third hollow convex partsand) that are formed in a first direction relative to a forming base surfaceorand that contact with the object to be packedto hold the object to be packedand second hollow convex partsand(the fourth hollow convex partsand) that are formed in a second direction opposite to the first direction relative to the forming base surfaceorand that contact inside the pack. The packing buffer memberoris formed by a plastic sheet.

Packing buffer member

A charging device includes a charging circuit for performing a charging action on a secondary battery, a power supplying circuit for supplying power to a load device connected to the charging device, a mode change-over circuit for selection from between a charge mode in which the charging action on the secondary battery is performed and a discharge mode in which power is supplied to the load device, and a control circuit for, when the charge mode is selected by the mode change-over circuit, causing the charging circuit to perform the charging action on the secondary battery and for, when the discharge mode is selected by the mode change-over circuit, causing the power supplying circuit to supply power from the secondary battery to the load device in a state in which the secondary battery is mounted on the charging device.

Combination battery charger and battery driven power supply

A waterproof case for housing a camera therein is provided with an operation part which is disposed on the waterproof case, and a signal transmission circuit which is arranged to transmit a signal output of the operation part to the camera housed in the waterproof case.

Waterproof case for camera

Moving elements in a recording and/or reproduction apparatus change the travel path of a strip-like recording medium mounted in a container. A detector detects a specified part of parts of the medium having a character different from other parts of the medium and at least part of a light emitting and/or light receiving arrangement of the detector moves into and out of the space required for altering the path of the medium.

Recording or reproducing apparatus using container mounted strip-like

A tape recording and/or reproducing apparatus in which a record bearing tape is wrapped about a cylindrical body and signal recording and/or reproduction is performed by rotating heads. A carriage carrying a tape wrapping member is moved by a movable member to a predetermined position to wrap the tape about the cylindrical body. A connecting rod connects the carriage and the movable member so that the rod extends almost perpendicular to a plane of the carriage and loosely engages either the carriage or the movable member. When the carriage is stopped at the predetermined position by a stopper while the movable member is slightly overdriven or over-moved, the connecting rod exerts a moment on the carriage and secures the carriage firmly at the predetermined position.

Recording and/or reproducing apparatus including device for securing a

A rotating head assembly comprises a fixed lower drum; a rotating member which has at least one head and also has a void hole in a position corresponding to the axis of rotation; supporting means which is disposed in a position farther away from the axis of rotation than the void hole and is arranged to support the rotating member rotatably relative to the fixed lower drum; and at least one composing means which is arranged by utilizing the void hole to compose at least a portion of the rotating head assembly.

Rotating head assembly

A rotary head device for a rotary head-type magnetic recording/reproducing apparatus comprising a fixed drum and a rotary member which has a magnetic head disposed therein is provided with a ball bearing which is formed by inserting a plurality of rolling members into annular grooves which are respectively formed in the fixed drum and the rotary member on their opposed sides and are located adjacently to their peripheries.

Rotary head device

In the disclosed video signal recording and reproducing apparatus, a cylinder member arranged to have a tape-shaped recording medium wound thereon, includes five rotating heads. The first head has a specific head width and azimuth angle. The second rotating head is approximately equal in head width to the first rotating head but differs from the first rotating head in azimuth angle. The third rotating head has a narrower head width than the first rotating head but is equal to the first head in azimuth angle. The fourth rotating head is approximately equal in head width to the third rotating head and equal in azimuth angle to the second rotating head and the fifth rotating head is equal in azimuth angle to the third rotating head.

Rotatable cylinder with plural heads having diverse azimuth angle gap

A color video camera includes an image pick-up device for converting images into electrical signals including a plurality of color signal elements, white picture forming circuitry for introducing a white picture to the image pick-up device and a white balance control for controlling a proportion of each color signal element contained in an output of the image pick-up device so as to have a prescribed ratio. A power source switch is included for supplying current to individual circuits in the video camera. The camera also includes an operation member having three positions. The member turns off the power source switch in a first position; it turns on the switch in a second position to control the white picture forming circuitry and introduces the white picture to the image pick-up device, thereby actuating the white balance control; in a third position it turns on the power source switch to control the white picture forming circuitry so as to prevent introduction of the white picture to the image pick-up device. The second position is located between the first and third positions.
