Abstract

PURPOSE:To obtain a lock device capable of locking and unlocking a cartridge from the main body of a machine, by detachably fitting to the main body of the machine the lock device having a lock pin capable of being engaged with a lock hole provided at a side part of the cartridge. CONSTITUTION:A take-up roll 7 and a pay-out roll 8 of an ink donor film 4 are fitted through shafts to a frame 6 of a cartridge 5. A pair of lock holes 9, 11 for locking the cartridge 5 to a main body 2 are bored respectively in both side parts of a front part of the cartridge 5. To lock the cartridge 5 to the main body 2, a key 33 is operated to turn an operating member 32 in the direction of an arrow 35. By the turning, pins 23, 24 are moved respectively in the directions of arrows 36, 37, and lock pins 15, 18 integral with the pins 23, 24 are moved in the same directions to be engaged with the lock holes 9, 11, whereby the cartridge 5 is locked to the main body 2. The cartridge 5 is easily unlocked by operating the key 33 to turn the operating member 32 in the direction opposite to the arrow 35.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for locking or unlocking a power cartridge containing a roll of ink donor film from a machine body.

``Prior Art'' In recording devices such as facsimile machines, recording is performed by heating a thermal head that is in contact with an ink donor film in a state where paper and ink donor film are superimposed in response to an image signal. Forming an image on paper. The ink donor film is supplied from a supply roll and wound onto a take-up roll. The above supply roll and take-up roll are stored in a cartridge in advance,
A type of recording apparatus is provided in which when the ink donor film runs out, the cartridge itself is replaced in the main body of the machine and the ink donor film is replenished.

``Problems to be Solved by the Invention'' The conventional ink donor film mentioned above could be easily taken out of the machine body along with the cartridge, so it is possible to read confidential information by reading the image transfer part of the ink donor film. The drawback was that it could be deciphered. There was a problem in that equipping a used cartridge with a locking mechanism to prevent this would be expensive and impractical.

SUMMARY OF THE INVENTION An object of the present invention is to provide a locking device capable of locking or unlocking a cartridge containing an ink donor film with respect to a machine body.

"Means for Solving the Problems" The cartridge locking device of the present invention has a vertically oriented substrate that is detachably attached to the main body of the machine, and a locking pin that can be coupled to the locking hole of the cartridge at the outer end. With,
A pair of slide levers that are laterally movably attached to the board and are biased in a direction in which the lock pins are removed from the locking holes, and a pair of slide levers that engage with pins fixed at appropriate positions on each slide lever. The cartridge has an engaging claw on its circumferential surface, and an operating member that moves the slide lever laterally by operating a key from the outside to lock or release the cartridge using the lock pin. It is said that

"Example" Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIG. 1, the upper part of a machine main body (hereinafter referred to as main body) 2 of a recording apparatus 1 can be opened and closed by a cover 3. As shown in FIG. A cartridge 5 having an ink donor film 4 is removably installed in the recording apparatus l.

A take-up roll 7 and a supply roll 8 of an ink donor film 40 are each pivotally attached to a frame 6 of the cartridge 5 shown in FIG. A pair of locking holes 9 and 11, which are used when locking the cartridge 5 to the main body 2, are formed on both sides of the front side of the cartridge 5, respectively.

FIG. 3 is a perspective view of the inside of the recording apparatus I seen from the rear. The base plate 13 of the locking device 12 can be detachably attached to the side plates 2a, 2b of the main body 20 by screws 14 using bent pieces 13a, 13b formed on both sides thereof. A horizontal slide member 16 having an inward locking pin 15 at its outer end locks the board 13 by fitting a plurality of elongated holes formed therein into a plurality of pins 17 fixed to the board 13. It is attached to the rear so that it can move laterally. A horizontal slide member 19 having an inward lock pin 18 at its outer end opposite to the lock pin 15 has a plurality of elongated holes drilled therein, which is fixed to a support plate 21 integral with the base plate 13. By fitting into a plurality of pins 22, it is attached to the rear surface of the board 13 so as to be able to move laterally.

As shown in FIG. 4, pins 23, 24 are fixed at appropriate positions on both slide members 16, 19, respectively. The slide member 16 is biased in a direction in which the lock pin 15 moves outward by the elasticity of a tension spring 25 whose both ends are locked to the base plate 13 and the pin 23, respectively. Similarly, the slide member 19 is biased in a direction in which the lock pin 18 moves outward by the elasticity of a tension spring 26 whose both ends are locked to the base plate 13 and the pin 24, respectively. A key device 27 is fixed to the support plate 21 that is integrated with the substrate 13, and this key device 27 is attached to the front plate 2C of the main body 2 as shown in FIG.
It is exposed to the front through a hole 28 bored in the.

As shown in FIG. 3, an actuating member 32 having a plurality of locking pawls 29.31 on its circumference that abuts against the pin 23.24 is fixed to the shaft 29 extending rearward of the key device 27. The operating member 32 is configured to rotate integrally when a key 33 shown in FIG. 1 is inserted into the key device 27 and rotated. In addition, in the case of the existing recording device 1 that does not include the locking device 12, a block plate 34 shown by a chain line is formed by a plurality of slits in the front plate 2C, and this block plate 34 can be removed if necessary. This allows the hole 28 to be easily formed.

In the lock device configured as described above, the lock pins 15, 18 are spaced apart from each other by the tension springs 25, 26, and when the cartridge 5 is installed in the recording device 1, the lock pins 15, 18 are located at positions separated from each other by the tension springs 25, 26, and when the cartridge 5 is installed in the recording device 1, the locking holes 9. 11 have lock pins 15 and 18 facing each other.

In this state, when the cartridge 5 is to be locked to the main body 2, the key 33 is operated to rotate the actuating member 32 in the direction of the arrow 35 in FIG. This rotation moves pins 23 and 24 in the directions of arrows 36 and 37, respectively.
Locking pins 1.5.18 integral therewith move in the same direction and engage the respective locking holes 9.11 to lock the cartridge 5 to the body 2. To release this lock,
This is easily accomplished by rotating the actuating member 32 in the direction opposite to the arrow 34 by operating the key 33.

If you want to add the lock device 12 to an existing recording device 1 that is not equipped with the lock device 12, remove the block plate 34 of the front plate 2C to form the hole 28, and attach the lock device 12 to the main body 2. All you have to do is put it on.

``Effects of the Invention'' As explained above, according to the present invention, a locking device having a locking pin that can be engaged with a locking hole provided on the side of a cartridge is removably provided in the main body of the machine, thereby making it possible to secure security. The ink donor film within the cartridge can be freely managed depending on whether retention is necessary or not. Furthermore, a locking device can be easily added to an existing recording device that is not equipped with a locking device according to a user's request.
