A disk cartridge is provided which includes an optical disk (2), a cartridge body (5) having formed therein a head opening (13) through which a part of the optical disk (2) is exposed to outside in a range between the inner and outer radii thereof, a shutter member (15) supported movably on the cartridge body (5) to uncover and cover the head opening (13), and a two-way forcing mechanism (38) to force the shutter member (15) toward any selected one of positions to cover and uncover the head opening (13). The two-way forcing mechanism (38) forces the shutter member (15) toward any selected one of the positions to cover and uncover the head opening (13) correspondingly to a position of the shutter member (15) relative to the head opening (13).

A printer apparatus is disclosed. The printer includes: a thermal head having heat generating elements arranged in the form of a line extending longer than the width of a printing medium in the width direction of the printing medium substantially orthogonal to the conveying direction thereof; and a platen disposed opposite to the thermal head with a conveying path for the printing medium interposed between them so as to cooperate with the platen to sandwich the printing medium beyond the width of the printing medium with an ink ribbon interposed. The platen is put in contact with an end portion of the thermal head located beyond the width of the printing medium.

When an interruption instruction occurs in an information processing apparatus including a CPU and a coprocessor, execution of a single dedicated instruction “GETACX Dm,Dn” performs saving of necessary data from all registers. “Dm” is a value output from a general register group 104 to a first data input bus 120. Each of calculation units implemented in a coprocessor 110 recognizes a value stored therein. If a value “Dm” specifies one of the calculation units, the specified calculation unit outputs, to a selector 116, data stored in a register included in the specified calculation unit. An implemented calculation unit information output circuit 117 stores therein the count of the calculation units implemented in the coprocessor 110. If a value of the first data input bus 120 is greater than the count of the calculation units, the implemented calculation unit information output circuit 117 outputs a value “1” to a flag register 102. Based on the fact that the value stored on the flag register 102 is “1”, a CPU 100 recognizes that saving of the data from the register has been completed.

Disclosed herein is a disk cartridge including a disk; a cartridge body in which the disk is rotatably accommodated, the cartridge body having a recording and/or reproducing window for exposing a part of the disk; a shutter mounted on the cartridge body so as to be movable between a closed position where the window is closed by the shutter and an open position where the window is opened by sliding the shutter; a shutter locking member adapted to engage a locking portion of the cartridge body when the shutter is in the closed position, thereby limiting the movement of the shutter in the direction of opening the window; a biasing member provided on the shutter for biasing the shutter locking member in the direction of engaging the shutter locking member with the locking portion of the cartridge body; and a deformation preventing member provided in the cartridge body at a position inside of the biasing member for preventing the deformation of the biasing member inward of the cartridge body.

A disk recording/reproducing apparatus includes a chassis rotatably supporting a holder for storing a disk cartridge; an eject lever movably disposed in the chassis in an insertion/removal direction of the disk cartridge and movably in a direction toward or away from the chassis. The eject lever is rotated by being pushed by the disk cartridge 1 inserted into the holder. A cartridge drop preventive mechanism prevents the disk cartridge ejected by the eject lever from dropping from the cartridge holder. The cartridge drop preventive mechanism is formed from a flat spring disposed on one side surface of the holder and makes a sliding contact with one side surface of the disk cartridge during unloading of the cartridge so as to give the disk cartridge a braking force. This arrangement can prevent the disk cartridge from jumping out and dropping off from the cartridge holder during ejection.
