Description

  The present invention relates to a lock release mechanism for releasing two different locks and a printer apparatus provided with the lock release mechanism.

  Conventionally, various types of recording apparatuses have been proposed as means for printing images and characters on paper, and many printers that can be easily printed at home are widely used. In such a printer device, it is possible to perform printing by setting an ink ribbon and paper in the printer device, and taking an image from an external storage medium or an external storage device and selecting it. Among such types of printers, there is a sublimation type printer device in which ink ribbons and paper sheets mounted in dedicated cassettes are loaded into the apparatus main body and used.

  In such a printer device having a detachable ink ribbon cassette and paper cassette, when it is desired to replace the ink ribbon cassette and paper cassette at the same time, it is necessary to operate and remove each cassette separately.

  On the other hand, as an example of releasing a plurality of locks with a single lever, in Patent Document 1, a first unit (outer blade holder) and a second unit (outer blade cassette) are connected to the main body (razor head). There is a configuration that can be individually separated and simplifies the locking mechanism. This makes it possible to unlock one of the first unit and the second unit, or to unlock both lock states simultaneously with one operating member. A first engagement body that locks and holds the first unit and a second engagement body that locks and holds the second unit are engaged with the operation buttons. When the operation button is pushed in the same direction, the first release position for releasing the first engagement body and the second release position for releasing the second engagement body can be operated. .

In this case, there is no problem because the second engagement body is released before the first engagement body. However, to release the first unit to release the first unit, the second engagement body is released first, so to unlock the first unit, The lock of the second unit will also be released. Therefore, it is possible to release one lock and two locks at the same time, but it is not possible to release the other lock which is completely functional.

  Therefore, the present invention solves the above-mentioned problems, and its purpose is to simultaneously release two different locks by operating one operation member in different directions, and to separate only the desired locks. It is an object of the present invention to provide a lock mechanism that can be released.

In order to achieve the above object, the locking mechanism of the present invention comprises:
A first lock member that realizes the first lock; a second lock member that realizes a second lock different from the first lock; and an operation member that can slide and rotate. The first lock by the first lock member is released by sliding in the direction of, and the second lock is released by sliding the operation member in a second direction different from the first direction. By rotating the member, both the first lock by the first lock member and the second lock by the second lock member are released.

  According to the present invention, it is possible to simultaneously release two different locks and individually release a desired lock by operating the one operation member in different directions.

  In this embodiment, roll paper is used as recording paper, and a cutter unit 5 is provided in the printer 1. In a print head (not shown), the ink ribbon from the ink ribbon cassette is heated and thermally transferred to the roll paper drawn from the paper cassette, and image transfer is performed with yellow, magenta, cyan, and overcoat. Then, after printing on the roll paper, a cutter unit having a blade for cutting the roll paper in the vicinity of the paper discharge port in the printer 1 in order to cut the roll paper in the printed range into a predetermined size. 5 is provided. The printed roll paper is cut into a predetermined size by the cutter unit 5, is further conveyed, and is discharged out of the printer 1. The position configuration shown in FIG. 2 is a diagram of a standby state (locked state) when the printer 1 is not operating and the user does not operate the lock lever.

  The description when the ink ribbon cassette 2 and the paper cassette 3 are attached to the printer 1 will be described below. The cassette cover 13 provided on the side surface of the printer 1 is opened, and the ink ribbon cassette 2 loaded with the ink ribbon and the paper cassette 2 loaded with recording paper are loaded into the printer 1 from the opening of the printer 1. . Then, by inputting an instruction to start printing, a printing operation for printing ink on the ink ribbon onto the recording paper is started. When the ink ribbon cassette 2 and the paper cassette 3 are loaded into the printer 1, they are inserted along the guide holes 13a provided in the cassette cover 13 and the like in the X direction in FIG. When the ink ribbon cassette 2 is inserted in the X direction in FIG. 1, the ink ribbon cassette engaging portion 42a and the ink ribbon cassette 2 provided at the tip of the lock member 42 are engaged as shown in FIG. 2A. The printer 1 is configured to lock at a predetermined position inside the printer 1. Further, when the paper cassette 3 is inserted in the X direction in FIG. 1, as shown in FIG. 2A, the cassette engaging portion 42a provided at the tip of the lock member 42 is engaged with the paper cassette. Thus, the printer 1 is locked at a predetermined position inside the printer 1. This position is a position where the ink ribbon and the paper can be conveyed into the printer 1. If the ink ribbon or paper is not arranged at an appropriate position at the time of printing, an error occurs during conveyance. Therefore, the positions of the ink ribbon 2 and the paper cassette 3 are often required to be accurate. For this reason, when inserted in the X direction, the ink ribbon 2 and the paper cassette 3 are urged toward the printer 1 in the Y direction by a spring (not shown), and the cassette remains in a halfway position until locked by the lock member 42. Often not. The ink ribbon cassette 2 and the paper cassette 3 mounted on the printer 1 are each urged in the take-out direction. In this case, in order to stabilize the position of each cassette, there is a role to bring it to one side. Further, since the cassette is biased to the take-out side, a part of the cassette is automatically pushed out from the inside of the printer only by releasing the lock by the lock member 42, so that the cassette can be easily taken out. Can do.

  Each component configuration state when the ink ribbon cassette 2 is removed by operating the lock lever 41 is performed with reference to the ink ribbon cassette removal state of FIG. FIG. 4A is an overall configuration diagram when the ink ribbon cassette is removed, and FIG. 4B is a simplified enlarged view of the ink ribbon cassette removed state. The ink ribbon and paper are replaced by taking out the ink ribbon cassette 2 and the paper cassette 3. When the user operates the lever operation portion 41a in the direction A (downward direction) in FIG. 4A to slide the lock lever member 41, the cam follower 42c of the lock member 42 that locks the ink ribbon cassette 2 is used. However, it moves because it is in contact with the cam portion. That is, the lock member 42 moves in the direction A from the state of FIG. 2A in conjunction with the lock lever member 41 to the state of FIG. 4B, and the ink ribbon cassette 2 and the engaging portion 42a are moved. The lock is released by moving to a position where it does not interfere. At this time, as shown in FIG. 4B, the cam groove 41c and the cam follower 42c are in contact with each other, and the cam follower 42c is in contact with the end of the cam groove 41c opposite to the A direction. When the member 41 is moved in the A direction, the cam follower 42c is moved in the A direction. That is, following the movement of the lock lever member 41, the lock member 42 also moves in the direction of retreating from the ink ribbon cassette 2. At this time, the lock member 42 on the paper cassette 3 side is in a state where the cam follower 42d and the cam groove 41c are separated from each other. Although the lock member 42 on the paper cassette 3 side is biased in the A direction, the position is restricted by the lock member restricting portion 14a. ing. Further, since the link fitting groove 41b and the fitting boss 43b are fitted, when the lock lever member 41 is moved in the A direction, the link member 43 is moved following. When the lock lever member 41 is moved until the contact between the ink ribbon cassette engaging portion 42a and the ink ribbon cassette 2 is separated, the contact of the ink ribbon cassette engaging portion 42a holding the ink ribbon cassette 2 with the lock member 42 is separated. To do. Then, the lock of the ink ribbon cassette 2 is released, and the ink ribbon cassette can be taken out by being pushed from the printer 1 in the Y direction opposite to X in FIG. . The lock member 42 is urged in the direction of the ink ribbon cassette 2 storage portion (lock direction) by a lock member urging spring 44, and the lock lever member 41 is moved to the position of FIG. Is energized. Therefore, when the operation of the lock lever member 41 in the direction A is stopped, the spring urging force of the lock member urging spring 44 returns to the standby state as shown in FIG. FIG. 4 is a diagram showing a state when the ink ribbon cassette 2 is taken out, and the configuration for taking out the ink ribbon cassette 2 has been described above. However, the configuration when taking out the paper cassette 3 is also the same. When the ink ribbon cassette 2 was taken out, the lock lever member 41 was retracted from the ink ribbon cassette 2 housing portion, and the lock member 42 was retracted from the ink ribbon cassette 2 by operating in the A direction. On the other hand, when the paper cassette 3 is taken out, the lock lever member 41 is operated in the A ′ direction opposite to A. Then, the contact between the paper cassette 3 and the paper cassette engaging portion 42b is separated by operating in the A ′ direction opposite to the paper cassette 3 storing portion. Then, the paper cassette 3 is unlocked and can be taken out from the printer 1. When the lock lever 41 is slid in the A ′ direction, the follower 42d located at the rear end of the cam groove 41c in the A ′ direction comes into contact with the end of the cam groove 41c and moves in the A ′ direction. Moving. When the cam follower 42d moves in the A ′ direction by the cam groove 41c, the lock member 42 on the paper cassette side moves in the A ′ direction, and the lock of the paper cassette by the engaging portion 42b is released. Since the cam follower 42c is located at the end on the A ′ direction side, even if the lock lever 41 is slid in the A ′ direction, it does not interfere with the cam groove 41c and does not move. Alternatively, the lock member 42 on the ink ribbon cassette side is urged in the A ′ direction by the urging spring 44, but does not move by contacting the lock member restricting portion 14 a.

  A description of the configuration when the ink ribbon cassette 2 and the paper cassette 3 are taken out at the same time will be given with reference to FIG. FIG. 5A is an overall configuration diagram when the cassette is simultaneously taken out, and FIG. 5B is a simplified enlarged view of the cassette being simultaneously taken out. As shown in FIG. 5A, the lock member 42 is retracted from the ink ribbon cassette 2 and the paper cassette 3 when the lock lever member 41 is rotated in the direction B in the drawing. As shown in FIG. 5B, when the lock lever member 41 is rotated in the B direction, the cam follower 42c of the lock member 42 on the ink ribbon cassette 2 side and the cam follower 42d of the lock member 42 on the paper cassette 2 side are cam grooves 41c cam. Move while contacting the surface. The cam followers 42c and 42d have an elliptical cam structure that is guided by the cam groove and moves toward the center of rotation. As a result, the lock member 42 moves away from the storage portion of the ink ribbon cassette 2 and the storage portion of the paper cassette 3. Therefore, the ink ribbon cassette engaging portion 42a that is in contact with the ink ribbon cassette 2 and the paper cassette engaging portion 42d that is in contact with the paper cassette 3 are retracted and the contact is separated. As a result, both the ink ribbon cassette 2 and the paper cassette 3 are unlocked simultaneously, and both cassettes can be taken out. By the rotation of the lock lever member 41, the link member 43 also follows and moves. The shape of the link fitting groove 41b in which the lock lever member and the link member 43 are fitted is substantially rectangular, and the link member 43 moves in response to the vertical movement and the rotational movement of the lock lever member 41. It is configured to always move only in the vertical direction. As in the case where the cassettes are separately taken out, when the rotation direction operation of the lock lever member 41 is released, the lock member 42 is moved by the lock member biasing spring 44 and the lock lever member 41 is moved by the lock lever biasing spring 45 as shown in FIG. Such a standby state is maintained. In the present embodiment, the vertical movement of the lock lever member 41 that enables a configuration for taking out the ink ribbon cassette 2 and the paper cassette 3 separately, and one rotation of the lock lever member 41 for taking out both cassettes simultaneously. The direction is moving.

  When a printing operation is being executed by the printer 1, the ink ribbon stored in the ink ribbon cassette 2 is wound around the take-up bobbin, or the roll paper stored in the paper cassette 3 is stored in the printer 1. It is being transported. If the ink ribbon cassette 2 or the paper cassette 3 is taken out at such time, the roll paper conveyed in the printer 1 or the ink ribbon crimped by the printing mechanism section is clogged in the printer 1 and causes jamming. . In order to prevent this, an interlock mechanism is often provided that prevents the cassette from being removed during the printing operation. In the present embodiment, the interlock mechanism is performed using the lock lever member 41, the link member 43, and the cutter unit 5.

  FIG. 6A is an interlock schematic view of the schematic configuration of the printer 1 as viewed obliquely from above, and the interlock configuration of the present embodiment will be described using this drawing. The cutter unit 5 is a mechanism for cutting roll paper into an arbitrary length, and includes a cutter holder 51, a movable blade 52, and a fixed blade 53. For example, in the print standby state as shown in FIG. 2, foreign matter such as dust is mixed in the printer 1 so that the quality of the printed matter is not impaired, or the cutter blade is touched to prevent injury. Therefore, the movable blade 52 and the fixed blade 53 are closed in the cutter unit 5. When a printing start operation is performed by pressing a print button (not shown), the roll paper in the paper cassette 3 is conveyed into the printer 1, but is movable to open the roll paper conveyance path. The blade 52 is separated from the fixed blade 53, and the cutter unit 5 is opened. 6B, the link member 43 includes a lock groove 43c that engages with the movable blade 52. As shown in FIG. When the cutter unit 5 is opened, that is, at a position where the movable blade 52 is moved to the retracted state, the lock groove 43c of the link member 43 and the movable blade 52 are engaged as shown in FIG. When the link member 43 and the movable blade 52 of the cutter unit 5 are engaged with each other, the link member 43 is held in this state and cannot move, and is locked. When the link member 43 is locked, the lock lever member 41 fitted to the link member 43 cannot be moved, and cannot be operated and moved. When taking out the ink ribbon cassette 2 and the paper cassette 3, the lock lever member 41 is operated to unlock the lock member 42 and the cassette and take out. Therefore, when the lock lever member 41 cannot be operated, the ink ribbon cassette 2 and the paper cassette 3 cannot be taken out, and the lock cannot be released. As described above, when the printing operation is started, the cutter of the cutter unit 5 is moved to the open state, so that the movable blade 52 and the link member 43 are engaged and locked, and the ink ribbon cassette 2 and the paper cassette 3 are moved. It is in an interlocked state that cannot be taken out. When the printing operation is finished, the cutter unit 5 is held at the closed standby position, and therefore the movable blade 52 and the link member 43 are not engaged with each other. The paper cassette 3 can be taken out.

  In the present embodiment, the cutter unit 5 which is a part of the printing mechanism is engaged with the link member 43 so as to be interlocked so that the cassette cannot be taken out. A restricting mechanism that restricts the sliding and rotating operations of the lock lever may be realized by another configuration. Further, the regulating mechanism may be realized in conjunction with another printing mechanism such as a print head and a paper transport mechanism instead of the cutter unit. It is desirable to link with a printing mechanism that operates when a printing operation is performed.

  In the above-described embodiment, the printer having the lock mechanism of the present invention has been described. However, the lock release mechanism of the present invention can be applied to apparatuses other than the printer. Any device having two different locks can be applied.
