The first member 411 </ b> A protrudes rearward from the rear peripheral wall of the main body 44 of the battery 4 and the rear end of the lid 45. The first member 411A enters the main body entry portion 27 from the front. The cross-sectional shape of the first member 411A is substantially the same as the cross-sectional shape of the main body entry portion 27. Therefore, the movement of the battery 4 in the left-right direction is restricted in a state where the first member 411A has entered the main body entry portion 27.

  With reference to FIG.7 and FIG.8, the procedure in the case of removing the battery 4 from the accommodating part 25 of the main-body part 2 is demonstrated. The user holds the operation part 282 of the main body fixing part 28 in a state where the battery 4 is accommodated in the accommodation part 25 (see FIG. 8), and lifts it upward. The main body fixing portion 28 swings in the direction in which the main body protruding portion 281 moves upward against the urging force of the main body urging portion 283. As a result, as shown in FIG. 7, the main body protruding portion 281 does not protrude downward from the upper inner wall surface 251 of the accommodating portion 25. At the same time, the battery protruding portion 411 of the battery fixing portion 41 moves forward by the urging force of the battery urging portion 413. The first member 411 </ b> A does not protrude rearward from the rear peripheral wall of the main body 44 of the battery 4 and the rear end of the lid 45. As a result, the battery 4 can move in the right direction. The user removes the battery 4 from the storage unit 25 by holding the lid 45 and moving it to the right.

  As described above, in the printing apparatus 1, when all the main body 44 of the battery 4 is accommodated in the accommodating portion 25, the main body protruding portion 281 of the main body fixing portion 28 enters the battery entry portion 42, and the battery fixing portion 41. The first member 411 </ b> A of the battery protrusion 411 enters the main body entry portion 27. The battery 4 is fixed at two places with respect to the main body 2 of the printing apparatus 1. Therefore, the user can firmly fix the battery 4 to the main body 2. The main body protruding portion 281 is urged in the protruding direction by the main body urging portion 283. Therefore, when the user fixes the battery 4 to the main body 2, it is not necessary to manually move the main body protrusion 281 in the protrusion direction. Therefore, the user can easily fix the battery 4 to the main body 2.

  The battery fixing portion 41 has a swinging portion 412. The swinging portion 412 swings the third vertex 412D of the first member 412A upward in response to the contact of the main body protruding portion 281 that has entered the battery entering portion 42. The battery protruding portion 411 causes the first member 411A to protrude rearward of the battery 4 in response to the swinging portion 412 swinging as described above. As described above, the battery fixing portion 41 can easily move the first member 411A of the battery protruding portion 411 in the protruding direction in response to the main body protruding portion 281 entering the battery entering portion 42.

  The battery fixing part 41 has a battery urging part 413. The battery urging portion 413 urges the battery protruding portion 411 forward. Accordingly, when the main body protrusion 281 does not enter the battery entry portion 42, the battery protrusion 411 does not protrude from the battery 4 and does not enter the main body entry portion 27. Therefore, the user can easily remove the battery 4 from the main body 2 by switching from the state in which the main body protrusion 281 enters the battery entry portion 42 to the state in which the main body protrusion 281 enters the battery entry portion 42.

  Since the cross-sectional shape of the main body entry portion 27 is substantially the same as the cross-sectional shape of the first member 411A of the battery protruding portion 411, both the length of the main body entry portion 27 in the left-right direction and the length of the first member 411A in the left-right direction are both. Almost identical. Further, the width in the left-right direction of the battery entry portion 42 and the length in the left-right direction of the main body protruding portion 281 are substantially the same. In this case, the movement of the battery 4 in the left-right direction is appropriately restricted in a state where the first member 411A of the battery protruding portion 411 enters the main body entry portion 27 and the main body protrusion portion 281 enters the battery entry portion 42. . Accordingly, since the battery 4 can be more firmly fixed to the main body 2, the printing apparatus 1 can be appropriately driven by the power source of the battery 4.

  In addition, this invention is not limited to the said embodiment, A various change is possible. In the battery 4, a mechanism for causing the first member 411 </ b> A of the battery protruding portion 411 to protrude from the battery 4 in response to the main body protruding portion 281 entering the battery entering portion 42 is realized by a mechanism other than the swinging portion 412. May be. For example, in the battery 4, the battery protrusion 411 is brought into direct contact with the main body protrusion 281 that has entered the battery entry portion 42, and the main body protrusion 281 directly pushes out the first member 411 </ b> A, whereby the first member 411 </ b> A protrudes from the battery 4. You may let them.

  The battery 4 may be configured not to include the battery urging unit 413. For example, the user may manually switch from a state in which the battery protruding portion 411 protrudes to a state in which the battery protruding portion 411 does not protrude.

  The cross-sectional shape of the main body entry portion 27 and the cross-sectional shape of the first member 411A of the battery protruding portion 411 may not be substantially the same. The cross-sectional shape of the first member 411 </ b> A of the battery protruding portion 411 may be smaller than the cross-sectional shape of the main body entry portion 27.
