In addition, ink tanks 20b, 20m, 20c, and 20y are provided in the upper part of the apparatus, and are connected to the printer head 10 by a tube.

  The inner frame 1 b includes a paper feed tray 7 that stores the paper 15. The paper feed tray 7 is provided with a hopper 16 that lifts the front end of the paper 15 in the conveying direction obliquely upward, and feeds the stacked paper 15 one by one to the platen 4 side. A paper feed roller 17 is provided at the upper end of the hopper 16, and the paper 15 fed one by one to the platen 4 side by the paper feed roller 17 is further drawn out above the platen 4 by the feed roller 18. Then, an image is recorded by the print head 10 and pulled out to the paper discharge side by the paper discharge roller 19.

  A front cover 8 is provided on the front side of the casing body 1a, and operation buttons, drawer levers, and the like are provided on the front cover 8, and the inkjet printer 1 is operated by operating these buttons and levers. ing. At the time of printing, a part of the front cover 8 is further tilted to the front side to be in the state shown in FIG. 6, and the printed paper 15 is stacked on this part.

  A main board 14 on which an integrated circuit, a memory, and other elements that perform electrical processing are mounted is provided in the inner frame 1b and serves as a control unit of the ink jet printer 1. The main board 14 is provided with a connector 12, and electricity is supplied into the inkjet printer 1 by connecting the connector 12 and an external connection terminal 13 formed on the back surface of the housing body 1 a.

  A guide rail 3 is formed in the casing body 1a along the moving direction of the inner frame 1b. A guide member 21 provided on the inner frame 1b side is guided along the guide rail 3, and the inner frame 1b is It can be pulled out and stored from the housing body 1a.

  Next, operations and effects of the ink jet printer according to the present embodiment will be described. When a print start control signal is received from an external device such as a personal computer, the paper is fed from the paper feed tray 7 one by one. A predetermined ink is ejected from the print head 10 mounted on the carriage 11 that reciprocates in the main scanning direction with respect to the conveyed paper 15, and an image is formed on the paper 15.

  When a paper jam occurs in the inkjet printer 1, as shown in FIG. 7, when the front cover 8 of the housing body 1a is opened and the inner frame 1b is pulled toward the front side, the connector of the main board 14 is 12 and the external connection terminal 13 of the housing body 1a are disconnected, and the inner frame 1b can be pulled out from the housing body 1a. Further, the paper feed tray 7 can be pulled out toward the front side with respect to the inner frame 1b. Thus, by pulling out the inner frame 1b from the housing body 1a, as shown in FIG. 7A, a sufficient space is secured in both the up and down directions of the arrow, and the operator easily causes an error. 15 can be removed.

  As described above, in the present embodiment, the inner frame 1b including the paper feed tray 7 and the head unit 10 can be separated from the housing body 1a. Therefore, various cables including a power cord can be inserted and removed. The paper jam can be easily eliminated.

  Further, since the inner frame 1b can be brought into contact with and separated from the housing body 1a, even when other devices are placed above and below the ink jet printer 1, the paper can be easily moved without moving these devices. That is, it can be solved. At that time, since various wirings connected to the back surface are connected to the housing body 1a and are connected to the inner frame 1b via the connector 12, it is not necessary to insert / remove the wiring each time, and the work is simplified. Can be.

  Next, other embodiments will be described. In the following description, parts having the same functions and effects as those of the first embodiment described above are denoted by the same reference numerals, and detailed description of the parts is given. In the following description, differences from the first embodiment will be mainly described. As shown in FIG. 8, the second embodiment is different from the first embodiment in that the connector 12 connected to the external connection terminal 13 is provided on the front side. As shown in FIG. 8, the connector 12 is provided on the back surface of the front cover 8, and the extension cable 30 is provided on the external connection terminal 13. When the front cover 8 is closed, the power supply terminal 30a provided at the tip of the extension cable 30 and the main board 14 of the inner frame 1b are electrically connected.

  As described above, since the connector 12 is provided on the front cover 8, since the connector can be easily visually confirmed, the possibility of connection failure is low, and the connection itself can be easily performed.

  Next, a third embodiment will be described with reference to FIG. In 3rd Embodiment, the connector 12 is provided in the outer surface of the bottom part of the inner side frame 1b, and the electric power feeding part extended from the external connection terminal 13 is provided in the inner surface of the bottom part of the housing body 1a. In addition, the guide rail 3 provided on the housing body 1a has a configuration in which an end 3a on the back side is bent obliquely downward, and when the inner frame 1b is slid along the guide rail 3, the inner frame 1b is lowered. The connector 12 is connected to the power supply terminal 30a. When the inner frame 1b sinks down, the connector 12 is connected to the power supply terminal 30a. Therefore, the inner frame 1b can be connected with its own weight, reducing the possibility of causing a connection failure and operating for the operator. Cheap.

  The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. As shown in FIG. 10, the external connection terminal 13 of the housing body 1 a and the main board 14 of the inner frame 1 b do not have to be completely separated, and may be connected by the cable 40. In this case, the cable 40 only needs to have a length sufficient to pull out the inner frame 1b from the housing body 1a.

  The embodiment shown in FIG. 11 is configured such that the center of gravity of the entire apparatus is on the arrow side with respect to the alternate long and short dash line 35 in a state where the inner frame 1b is pulled out from the housing body 1a. By adopting such a configuration, the entire apparatus can be stably seated even when the inner frame 1b is pulled out, and a recording medium error can be solved more easily.

  In the embodiment shown in FIG. 12, the shape of the connector 12 is substantially trapezoidal. Thus, by making the shape of the connector 12 substantially trapezoidal, smooth connection is possible even if there is a slight left-right displacement.
