The present invention relates to a data processing device which is also used as an interface device for connecting an external storage device to a host computer to which a card form of storage device can be connected, the external storage device differing in data format from the card form of storage device. The data processing device includes a connection unit for connecting the external storage device to the host computer, the connection unit being able to be removably fitted into a slot which is provided in the host computer and into which to removably fit the card form of storage device, and a converting circuit for converting data, which is to be outputted from the host computer in a data format conforming to the card form of storage device, into a data format conforming to the external storage device, as well as for converting data read out from the external storage device into the data format conforming to the card form of storage device.

Interface with connection unit for loading host computer with external storage device format control information in response to connection of host computer to connection unit

An external peripheral device connects through a flexible cable to an electrical connector which connects to a computer system. The flexible cable wraps around a cable wrap member that protrudes out of the peripheral device's housing, and the electrical connector snaps into a connector holder built into the peripheral device's housing. The cable wrap member and the connector holder permit the secure storage of the flexible cable and electrical connector during non-use or transportation of the device.

Flexible disc drive

A head for writing data into and/or reading data out of a recording medium such as a magnetic disc is displaced along a path by a motor such as a voice coil motor. The moving member of the motor is disposed on one side of the path, and another moving member of a speed sensor for detecting the head displacement speed is disposed on the opposite side. As a result, an unbalanced mass arrangement with respect to the path along which the head is displaced will not occur. The signal from the speed sensor can be used, for example, to interrupt a write operation if a mechanical impact occurs. Furthermore, even in an embodiment in which a coil is wound around the moving member of the speed sensor so that the head displacement speed is detected as a voltage induced across the coil as the head is displaced, the motor and the speed sensor are disposed in spaced-apart-relationship with each other and the speed sensor is less susceptible to adverse effects caused by the leakage flux from the motor.

Recording and/or reproducing apparatus with sensor for detecting head

In a data writing and/or reading device in which data is written and/or read out from a rotating recording medium, a head carriage upon which one or more heads are mounted is guided by first and second guide rods to move in a predetermined direction with respect to the recording medium. A member for biasing the head carriage in the direction opposite the direction of a rotating force produced by the friction between the head or heads and the recording medium is provided. This force in the direction of rotation of the recording medium is counteracted so that deviation of the head in the direction of rotation of the recording medium is eliminated.

Head positioning apparatus

An apparatus for transporting, cleaning or performing recording and/or reproducing of information from a card-like medium is disclosed. The recording medium includes an information recording area and a non-recording area. The transporting apparatus includes a receiving transport device and a discharging transport device. The receiving transport device transports the recording medium into and within the apparatus. The discharging transport device discharges the card-like information recording medium outside the apparatus and includes transporting the recording medium and stopping the recording medium such that the information recording area remains within the apparatus. The apparatus for cleaning the recording medium includes a cleaning device for cleaning the recording medium, a moving device for moving the recording medium relative to the cleaning device and a receiving device for receiving the recording medium in the apparatus. A discharging device transports the recording medium and stops the medium so that the information recording area remains within the apparatus. The apparatus for recording information on and/or reproducing information from the recording medium includes a head unit for performing the recording and/or reproducing of information. A moving device moves the recording medium relative to the head unit and a receiving device receives the recording medium in the apparatus. The recording medium is discharged by a discharging device, so that the information recording area remains within the apparatus.

Apparatus for transporting card-like information recording medium

A cleaning device comprises a cleaning member having a cleaning surface adapted to abut against a recording surface of an information recording medium, apparatus for holding the cleaning member, apparatus for moving the cleaning surface of the cleaning member, and apparatus for moving the hold means relative to the recording surface.

Cleaning device for information recording medium

An information recording-reproducing apparatus comprises a head, a first pair of rollers for guide-driving a recording medium relative to the head, a second pair of rollers for guide-driving the recording medium toward or from the first pair of rollers, and a controller for timingly controlling the first and second pairs of rollers. The first and second pairs of rollers are disposed at such an interval that the recording medium may not be caught by both of the first and second pairs of rollers at a constant velocity movement of the recording medium.

Information recording-reproducing apparatus

In an apparatus for recording and reproducing information, an information recording medium is reciprocated relative to a head for effecting information recording and reproduction, under such conditions that one end of the recording medium is urged against a guide member extending in a direction of the reciprocation of the recording medium.

Apparatus for recording and reproducing information

There is disclosed an integrated cylindrical formation of plural lines of a printing type belt in such a printing type drum as contains a hammer unit therein, has plural lines of printing type belts installed round the periphery of the cylindrically formed drum body and supplied printing ink to the types by pressing an ink roller against the printing type belts.

This invention relates to a typefont belt and a typefont wheel for use in the small printer. The typefont belt made, for example of rubber, is fitted around a cylindrical support to compose the typefont wheel and is struck by a printing hammer provided in the support to perform printing on the printing sheet.
