  If the door opening / closing device having such a configuration can be used as an opening / closing device for a discharge stacker of an inkjet printer, it is considered that the opening / closing operation of the discharge stacker becomes more intuitive and easy to understand. However, in the case of a portable inkjet printer that is portable, it is difficult to secure a large space for accommodating the push latch device, and a push latch device having a more compact structure is required.

  In addition, when a push latch device is applied to a door body opening / closing device such as the discharge stacker, the door body has a long lateral width, and the device body cannot be provided at the center in the width direction. The following problems occur when there is a structural cause in Normally, an opening / closing device using a push latch device requires a push operation to the outer surface of the door body when the door body is opened and closed. Therefore, the rotation free end side of the door body is slightly bent backward and pushed in any position.

If the user pushes the location where the push latch device is located or close to it, the opening and closing operation is performed properly.For example, the end portion that is far away from the position where the push latch device is located with respect to the closed door body When pushed, there is a problem that the door can not be opened but can be pushed. This problem does not occur if the mark indicating the push position is written on the exterior surface portion of the door body. However, in the case of a device that cannot write such a mark, the above problem occurs. This problem can be said to be a problem peculiar to a push latch device that assumes a push operation, and the user feels uncomfortable that the door body does not open even though the door body is pushed to open the door body. . That is, there is a problem that the operability of opening and closing the door body is low and the product value is lowered.

  In the illustrated embodiment, when the discharge stacker 8 is in the closed state, the end surface 23a of the push-in rod 23 abuts the back surface 18 near the right corner at the free rotation end (near the front end surface 58) of the discharge stacker 8. The contact surface 92 of the contact portion 91 is set so as to contact the back surface 18 near the left corner portion at the rotation free end (near the front end surface 58) of the discharge stacker 8. When the discharge stacker 8 is closed, the discharge stacker 8 is stored in the recessed portion 16, and the back surface 18 of the discharge stacker 8 contacts the contact surface 92 of the contact portion 91 and the end surface 23 a of the push rod 23. The surface of the printer main body 3 and the surface of the discharge stacker 8 are configured to be flush with each other as shown in FIG.

  The force point F on the surface of the discharge stacker 8 that the user pushes to open the discharge stacker 8 is generally at a position intermediate between the end surface 23a of the push rod 23 and the contact surface 92. When this force point F is pressed, the pushing portion 91 side of the discharge stacker 8 is pressed (not moved) by the contacting surface 92, and the pushing rod 23 side of the discharging stacker 8 is pushed. It is. Thereby, the discharge stacker 8 can be expanded. In this way, the discharge stacker 8 can be expanded by intuitively pressing the surface of the discharge stacker 8 without the user being particularly conscious of the position of the force point F.

  Further, when the user temporarily presses the surface of the discharge stacker 8 on the side of the contact portion 91, it is realized that the discharge stacker 8 does not move and cannot be pushed in. With this actual feeling, the user naturally acts to push the position where the user moves, that is, the position where the discharge stacker 8 can be pushed. That is, it acts naturally so as to push the position on the push rod 23 side from the middle position in the left-right direction of the discharge stacker 8. Therefore, even if the user is not particularly aware of the position of the force point F, the discharge stacker 8 can be expanded by naturally pressing the appropriate position of the discharge stacker 8.

  Next, the operation mode of the discharge stacker opening / closing device 1 configured as described above will be described separately for (1) closing the discharge stacker and (2) opening the discharge stacker.

The push rod 23 protrudes greatly forward from a hole 31 formed in the front surface 20 of the recessed portion 16 of the printer body 3. On the other hand, at this time, the magnet holder 53 and the magnet 54 are positioned at the lowermost end by their own weight, and the bottom 57 of the magnet holder 53 slightly protrudes from the window 62 formed on the front surface 20 of the recessed portion 16. It has become.

  Then, when the discharge stacker 8 that is tilted forward is raised upward and the discharge stacker 8 is pushed into the recessed portion 16 of the printer body 3, the back surface 18 of the upper right corner portion of the discharge stacker 8 is pushed into the push rod 23. In contact with the end surface 23a, the push rod 23 is pushed backward as shown in FIGS. Then, the push rod 23 stops at the pushed position, and the discharge stacker 8 reaches the closed position and is closed.

  At this time, at least the back surface 18 of the upper left corner of the discharge stacker 8 also comes into contact with the contact surface 92 of the contact portion 91, so that the surface of the printer body 3 and the surface of the discharge stacker 8 are brought together. Become the same. In addition, the door body is further tilted inward in a closed state in which the back surface 18 of the upper right corner portion of the discharge stacker 8 is brought into contact with the end surface 23a of the pushing rod 23 and the door body is housed in the recessed portion 16. It is possible to make the surface of the printer main body 3 and the surface of the discharge stacker 8 flush with each other even by shifting the center of gravity.

  When the push rod 23 is pushed backward, the slider 24 integrated with the push rod 23 moves backward as shown in the figure against the biasing force of the bias spring 26. Further, the movement direction is limited by moving toward the closed position of the discharge stacker 8 with the front end surface 58 of the rotation free end of the discharge stacker 8 in contact with the bottom 57 of the magnet holder 53. The magnet holder 53 and the magnet 54 are moved upward to allow the discharge stacker 8 to move to the closed position.

  Further, as the slider 24 moves rearward, the swing arm 29 has the swing shaft 50 as the swing center, and the engagement shaft 28 at the tip is pushed from the holding point A to the push-in path 40 as shown by an arrow in FIG. First, it swings to the right so as to reach the holding point B, then swings to the left, and the push rod 23 is held at the pushed position shown in FIGS. In this state, the push rod 23 and the magnet holder 53 are all hidden by the discharge stacker 8, and the push rod 23 and the magnet holder 53 cannot be visually recognized from the outside.

(2) When the discharge stacker is opened (see FIGS. 4 to 7, 12, and 13)
A case will be described in which the discharge stacker 8 accommodated in the recessed portion 16 is tilted forward and opened to enable recording. In this case, as shown in FIG. 5, the surface of the discharge stacker 8 between the contact surface 92 and the end surface 23a of the push rod 23 is lightly pushed with a finger, and the push rod 23 and the slider 24 are moved slightly backward. . As the slider 24 moves rearward, the swing arm 29 swings clockwise in FIG. 12, and the engagement shaft 28 at the tip of the swing arm 29 moves diagonally to the left from the holding point B. To do.

  Subsequently, when the finger that pushed the surface of the discharge stacker 8 is released, the slider 24 moves forward by the urging force of the urging spring 26, and as shown in FIG. 28 leaves the holding point B and reaches the holding point A through the extrusion path 41 as indicated by an arrow in the figure. Then, the discharge stacker 8 is rotated toward the front side to be in an expanded state, and the recessed portion 16 of the printer main body 3 appears. The engagement shaft 28 that has once reached the holding point A cannot directly enter the extrusion path 41 by the step 42 provided in the overlapping portion between the push-in path 40 and the extrusion path 41. Therefore, the engagement shaft 28 can always rotate in the guide groove 27 only in the clockwise direction in FIGS.

  When the surface of the upper left corner portion of the discharge stacker 8 is pressed, the discharge stacker 8 cannot move backward due to the presence of the contact portion 91. Therefore, even if the user pushes the surface of the upper left corner portion of the discharge stacker 8, the discharge stacker 8 does not move and the user can feel that it cannot be pushed in. With this actual feeling, the user naturally acts to push the position where the user moves, that is, the position where the discharge stacker 8 can be pushed. That is, it acts naturally so as to push the position of the right upper corner portion from the middle position of the discharge stacker 8 in the left-right direction. Therefore, there is no discomfort in the pressing operation such that the discharge stacker 8 does not open despite being pressed.

  Further, in a state where the discharge stacker 8 is expanded, the magnet holder 53 and the magnet 54 move to the lowest end due to their own weight, and the bottom portion 57 of the magnet holder 53 from the window portion 62 formed on the front surface 20 of the recessed portion 16. Is slightly protruded, and the push rod 23 appears on the front surface 20 of the recessed portion 16 of the printer body 3, but the appearance of the printer body 3 is hardly affected.

[Other embodiments]
The door opening and closing device 1 according to the present invention and the recording device 100 and the like in which the door opening and closing device 1 is applied to the discharge stacker opening and closing device are based on the above-described configuration. Of course, it is possible to change or omit the partial configuration without departing from the scope of the invention. For example, the door opening and closing device 1 according to the present invention is not limited to a storage device such as the ink jet printer 100 and other liquid ejecting apparatuses, and the main body 3 and the door body 8 that is rotatably connected to the main body 3. And can be applied to various devices, storages, containers, and the like.

  Further, when it is desired to increase the urging force in the direction in which the slider 24 protrudes, the urging spring 26 can be contracted in both the two square grooves 32. Incidentally, when configured in this way, the urging force can be increased without increasing the coil diameter or wire diameter of the urging spring 26, and the thin shape of the push latch device 21 can be maintained as it is.

  Further, as the door body closed state holding means 80, a known structure integrated with the door body opening / closing means 70 may be employed instead of the magnet catch device 22. In this case, for example, a door body closed state holding means 80 is added to the push latch device 21.

In addition to the function of making the surface of the printer main body 3 and the surface of the discharge stacker 8 flush with each other, the contact portion 91 also functions as an inclination correction means (door inclination correction means) of the discharge stacker.
In addition, the shape, size, installation location, etc. of the contact portion 91 are determined by the distance between the contact portion 91 and the push rod 23, the shape and size of the door body 8, the depth of the recessed portion 16, and the like. Accordingly, it can be changed as appropriate in accordance with the object of the invention. It is also possible to form the contact portion 91 with the magnet 54 and to allow the contact portion 91 to have a function as the magnet catch device 22.
