As shown in FIG. 8, the movement restricting member 27 is movably supported in a direction approaching the tray portion 21 by a guide shaft 1J installed vertically from the main body 1 side. A rack 27A is formed at the side of the movement restricting member 27.

The power of the drive gear 15A is transmitted to the rack 27A through a gear train 28 rotatably supported from the main body 1 side, and the movement restricting member 27 is driven by the fire of the drive gear 15A. When the recording needles 18A, 18B, and 18C move toward the recording paper C, they move approximately in synchronism with the movement and approach the tray 21 at approximately the same speed.

Similarly, when the recording needles 18A, 18B, and 18C move in the direction away from the recording paper C, the movement restricting member 27 is substantially synchronized with the movement and separated from the tray portion 21 at approximately the same speed. Move in the direction of

As shown in FIG. 2, the distal end of the movement restricting member 27 is disposed below the distal end of the recording needles 18A, 18B, and 18C. Before the 18A, 18B, and 18C contact the recording paper C, they are engaged with the engaging recess 21F of the tray 21, and the recording needles 18A, 18B, and 18C are separated from the recording paper C. Afterwards, it is separated from the engaging recess 21F.

As is apparent from the above description, in the present embodiment, the recording needles 18A, 18B, 18C, the guide shaft 1J, the movement restricting member 27, and the gear train 28 from the plurality of elements shown in FIG. The recording needle moving means 5 for moving the recording needles 18A, 18B, and 18C in the direction away from the recording paper C is composed of the remaining elements except the guide shaft 1J and the movement restricting member. (27) and the gear train 28 constitute a support state guarantee means 6.

Next, the operation (action) will be described.

First, as shown in FIG. 1 and FIG. 2, the tray part 21 is pulled out from the recording sheet exchange place, and the recording sheet C is attached to the recording sheet attachment plate 22. As shown in FIG.

In this state, the recording needle elevating cams 16A and 16B are at the positions shown in FIG. 9A, respectively. Therefore, as shown in FIG. 2, the recording needles 18A, 18B and 18C are It is located at a point in the main body 1 which is higher than the recording paper C on the tray part 21 of the information recording location, and the movement restricting member 27 is similarly located above the tray part 21 of the information recording location. (1) It is located in place.

Next, the key is inserted into the keyhole 24a, and the lock 24 is rotated from the locked position 24b to the open position 24c, so that the operator 25 is displayed as shown by the imaginary line in FIG. The front panel 21E is pushed while being positioned inside the panel 21E.

As a result, the tray 21 moves from the recording paper exchange location toward the information recording location while winding the coil spring at the bottom, and when the information recording location is reached, the engaging projection 21B abuts against the latch member 1B. The latch member 1D is pushed into the housing 1C and immersed.

The two engagement pieces 1E are then pulled from the source into the housing IC, so that each engagement piece 1E is engaged with the engagement protrusion 21B as shown in FIG. The latching member 1D is supported in the housing 1C by the latch mechanism, so that the engaging projection 21B is pressed in the direction in which the tray portion 21 is pushed toward the recording paper exchange place by the coil spring at the bottom. ) And the latch mechanism 1B are supported at the information recording location.

Next, the lock 24 is rotated from the open position 24c to the locked position 24b with the key, and the key is removed from the keyhole 24a.

Then, the operator 25 protrudes outward from the right end of the front panel 21E as shown by the solid line in FIG. 6 to push the spring plate 26C from below.

As a result, the button 26B is pushed into the main body 26A, the electrical contact (not shown) inside the main body 26A conducts, and the motor 11 is controlled based on the output from the switch 26. The output shaft 11a of the motor 11 is rotated a predetermined amount in the counterclockwise rotation direction in FIG.

The motor 11 rotates by a predetermined amount, and the recording needle lifting cam 16A rotates 180 ° clockwise in the same figure from the position shown in FIG. 9A. Similarly, the recording raising and lowering cam 16B rotates. If the rocking rods 17A, 17B, 17C oscillate in accordance with the operation of the cam followers 17Aa, 17Ba, 17Ca while rotating 180 ° in the counterclockwise direction in the figure from the position shown in FIG. 9 (a). , The recording needles 18A, 18B, and 18C and the movement restricting member 27 move in the direction approaching the tray portion 21.

Since the tip of the movement restricting member 27 is disposed below the tip of the recording needles 18A, 18B, and 18C, the movement restricting member 27 first moves during the rotation of the recording needle lifting cams 16A, 16B. After engagement with the engaging recess 21F of the tray 21 and the removal of the tray 21 from the information recording point becomes impossible, the recording needle lifting cams 16A and 16B are rotated approximately 180 degrees. At this point, the recording needles 18A, 18B, and 18C come into contact with the recording paper C, and are in the state shown in FIG.

Thereafter, the recording sheet attachment plate 22 starts to rotate by a rotation drive source (not shown), whereby the recording of each piece of information on the traveling distance, the crew shift, and the traveling speed on the recording sheet C is started.

Next, when information recording on the recording sheet C is finished and the recording sheet C is taken out, a key is inserted into the keyhole 24a to rotate the lock 24 from the locking position 24b to the open position 24c. .

Then, as the operator 25 indicates by the imaginary line in FIG. 6, the button 26B pushed away from the spring plate 26C and pushed into the main body 26A is returned, and the electrical contact (inside the main body 26A) (Not shown) is opened, and the motor 11 is controlled based on the change of the output signal of the switch 26, so that the output shaft 11a of the motor 11 is rotated in the clockwise direction in the eighth degree. Quantitative rotation.

By the rotation of the motor 11, an operation opposite to the above-described operation in which the recording needles 18A, 18B, and 18C and the moving regulating member 27 approach the tray portion 21 is performed. The recording needles 18A, 18B, and 18C are first separated from the recording paper C, and then the movement restricting member 27 is separated from the engaging recess 21F of the tray portion 21 so that the information of the tray portion 21 can be obtained. Extraction from the recording point becomes possible.

When the tray 21 is pushed in here, the support of the latch member 1D by the latch mechanism is released, and the latch member 1D is moved forward from the housing 1C by the elastic force of the spring inside the housing 1C. And the engaging piece 1E and the engaging projection 21B are released.

As a result, the pinion 21A starts to rotate by the elastic force of the coil spring at the bottom of the tray 21, and the tray 21 moves toward the recording paper exchange point by engaging the rack 1A.

When the tray portion 21 reaches the recording sheet exchange point as shown in FIG. 3, the recording sheet C is peeled off from the recording sheet attachment plate 22, or the tray portion 21 is replaced by a new recording sheet C. After moving from the recording paper exchange point toward the information recording point and supporting it at the information recording point by engaging the engaging projection 21B and the latch mechanism 1B, the lock 24 is opened with a key in the open position 24c. From the key hole 24a to rotate the lock position 24b.

At this time, by the output of the switch 26, the recording needles 18A, 18B, and 18C move to the tray section 21 together with the movement restricting member 27, but the new recording paper is attached to the recording sheet attachment plate 22. When (C) is not attached, the tip ends of the recording needles 18A, 18B, and 18C are stopped at a position slightly separated from the tray portion 21 and do not come into contact with the tray portion 21.

Then, in case, a means for detecting the presence or absence of the recording sheet C on the tray 21 is provided, and the tray 21 is supported at the information recording point, and then the lock 24 is locked at the lock position 24b. If there is no recording paper C on the tray 21 in the rotated state, control of the motor 11 based on the output of the switch 26 may be cancelled.

In this way, according to this embodiment, the tray 21 is moved from the recording sheet exchange point and locked from the open position 24c of the lock 24, which is subsequently carried out by the latch mechanism 1B at the information recording position. The switch 26 was detected by the rotation to 24b, and after this detection, the recording needles 18A, 18B, and 18C were moved to contact the recording paper C.

When the tray 21 is taken out from the information recording point to the recording paper exchange point, the switch 26 detects that the lock 24 is rotated from the lock position 24 to the open position 24c by a key. After the detection, the movement restricting member 27 that is engaged with the engaging recess 21F of the tray 21 in advance is detached from the engaging recess 21F, and the tray 21 can be removed. The recording needles 18A, 18B, and 18C were to be separated from the recording paper C prior to

For this reason, the tray part 21 can be prevented from going in and out while the recording needles 18A, 18B, and 18C are in contact with the recording paper C, and accordingly, the recording paper can be prevented from entering and exiting the tray part 21. The recording needles 18A, 18B and 18C can be reliably folded without interfering with (C).

In this embodiment, the lock 24 is opened later than the point in time when the recording needles 18A, 18B, and 18C are brought into contact with the recording paper C by the latch mechanism at the information recording point. Although the case where the rotation is performed from the position 24e to the locked position 24b has been described, the timing of starting the contact operation of the recording needles 18A, 18B, and 18C to the recording paper C is the timing illustrated in this embodiment. It is not limited to.

For example, a detection mechanism such as a limit switch that detects that the latch mechanism 15 supports the tray portion 21 at the information recording location is provided, and the recording is immediately performed at the time when the tray portion 21 is supported at the gutter location. The needles 18A, 18B, and 18C may be configured to perform contact operation with the recording paper C.

Further, in this embodiment, the support state guarantee means 6 is made so that the recording needles 18A, 18B, and 18C can be taken out from the information recording place of the tray 21 to the recording paper exchange point after the recording needles 18A, 18B, and 18C are separated from the recording paper C. And move the movement restricting member 27 in the supporting state guarantee means 6 toward the engagement recess 21F simultaneously with the contact operation of the recording needles 18A, 18B, and 18C to the recording paper C. Although it is set as the starting structure, the engagement operation | movement to the engagement recessed part 21F to the movement restricting member 27 is not limited to the timing illustrated by this embodiment.

In other words, if the latch mechanism 18 supports the tread portion 21 at the information recording location, the contact mechanism 18A, 18B, 18C may be before or after the contact operation of the recording paper C.

In this embodiment, the tray portion 21 is pressurized in the direction moving from the information recording point to the recording paper exchange point by the coil spring at the bottom thereof, but the tray portion 21 is pulled out by the tray part by hand. The coil springs of the tray portion 21 can be omitted.

In addition, the tray 21 may be automatically moved in and out by using a power transmission mechanism such as a motor and a gear group.

In this case, the means for supporting the tray section 21 at the information recording location can be constituted by a member which selectively engages with the constituent members in the power transmission mechanism to restrict its operation.

Alternatively, the tray 21 can be supported by the mechanical load applied to the output shaft when the motor stops when the tray 21 reaches the information recording point so that the tray 21 can be supported in a non-movable state. It may be.

Moreover, in addition to the example which comprises a support means by the drive system of the tray part 21 mentioned above, the click mechanism provided in either the main body 1 and the tray part 21 is made to hang the other side, and the click mechanism You may comprise a support means.

In addition, the front panel 21E is omitted from the tray portion 21, and instead, a lid for opening and closing the doorway 1a is attached to the main body 1 via a hinge, and the lid is closed by a lock. It is comprised so that a key may be latched and this closed cover body may be used as a support means.

In this way, the configuration of the means for supporting the tray section 21 at the information recording location is not limited to the configuration illustrated in this embodiment, but is arbitrary.

In addition, in this embodiment, although the lock 24 is attached to the tray part 21 and the switch 26 is attached to the main body 1, the arrangement of the lock 24 and the switch 26 is arbitrary, and the main body ( Either one may be provided in either one of the 1) and the tray part 21, or the lock 24 is attached to the main body 1, and the switch 26 is attached to the tray part 21, as opposed to the present embodiment. You may install it.

The means for detecting the open / closed state of the lock 24 is not limited to that of a contact type represented by a micro switch such as the switch 26 exemplified in this embodiment, and a contactless type represented by a photointerrupter is used, for example. You may also do it.

The configuration of the lock 24 is not limited to the configuration in which the cylinder rotates as exemplified in the present example, and is arbitrary.

In this embodiment, the key is taken out of the keyhole 24a of the lock 24 rotated to the lock position 24b during recording of information on the recording paper C by the recording needles 18A, 18B, and 18C. However, it is arbitrary to remove the key from the keyhole 24a or to insert it into the keyhole 24a during recording the information on the recording paper C.
