According to an embodiment, a wireless tag communication device includes a first antenna that emits radio waves towards a first region of a conveyance path for wireless tags and a second antenna that emits radio waves towards a second region of the conveyance path on downstream of the first region along the conveyance path. A shield prevents the radio waves emitted from the first antenna from reaching a first portion of the first region while permitting the radio waves to reach a second portion of the first region. A controller is configured to select a tag ID read via the first antenna as a target tag ID, designate the target tag ID by communication via the second antenna, and then write tag information via the second antenna to the wireless tag corresponding to the designated target tag ID.

According to an embodiment, a cart gate for storage of carts that have a power reception device includes a pair of guides spaced from each other in a cart-width direction. The guides extend along a forward cart direction. A power transmission device is mounted on a portion of one of the guides. The power transmission device is configured to provide power, in a non-contact manner, to a power reception device on a cart that is between the pair of guides and at a predetermined cart storage position along the forward cart direction. The minimum distance between the guides in the cart-width direction is greater than a width of the cart, but the difference between the minimum distance and the width of the cart is less than or equal to a power transmitting range of the power transmission device.
